Memory functions can be considerably affected by various life events and stress has shown to be a chief regulator. Different stress patterns have distinct effects on the overall functioning of the brain. Stress provokes inflammation not only in the periphery but also in the brain. Neuroinflammation causes alterations in neuronal structure and function, which eventually progress to the development of neurodegenerative diseases. Inflammatory reactions are modulated through communication between the nervous, endocrine and immune systems...

Classic antidepressant drugs are modestly effective across the population and most are associated with intolerable side effects. Recently, numerous lines of evidence suggest that resveratrol (RES), a natural polyphenol, possesses beneficial therapeutic activity for depression. The aim of the present study was to explore whether RES exhibits an antidepressant-like effect in a depression model and to explore the possible mechanism. A depression model was established via chronic unpredictable mild stress (CUMS), after which the model rats in the RES and fluoxetine groups received a daily injection of RES or fluoxetine, respectively...

The complex bidirectional communication between the gut and the brain is finely orchestrated by different systems, including the endocrine, immune, autonomic, and enteric nervous systems. Moreover, increasing evidence supports the role of the microbiome and microbiota-derived molecules in regulating such interactions; however, the mechanisms underpinning such effects are only beginning to be resolved. Microbiota-gut peptide interactions are poised to be of great significance in the regulation of gut-brain signaling...

Total mixed rations (TMR) are commonly fed to dairy cows with a goal of reducing ruminal acidosis, but the daily pattern of feed intake has major implication for rumen fermentation and postabsorptive physiology. Generally there is low feed intake during the overnight period and high intake after feeding and during the afternoon. The objective of this study was to determine if feeding a partial mixed ration (PMR) plus a high starch top-dress before feeding of the PMR would improve production and modify key daily rhythms...

Primary polydipsia (PP) has been defined as excessive intake of fluids. However, the pathogenesis of PP remains unexplored. Different theories include a dysfunction in the thirst mechanism, involvement of the hippocampus, stress-reducing behaviour and lesion occurrences in specific areas of the brain. Most studies have been performed in the psychiatric setting, indicating that PP coincides with schizophrenia, anxiety disorder and depression. However, an increasing number of case reports emphasise the incidence of PP in non-psychiatric patients...

BACKGROUND: Several studies have shown a positive association between depression and obesity; however the underlying mechanisms are not fully understood. It is not known if this association is driven by altered sex hormone levels in men due to increased BMI. PATIENTS AND METHODS: Data were obtained from the LIFE-Adult-Study, a population-based cohort study. A total of 3925 men (2244<60years and 1681>60years) were included into analyses. Associations between BMI, sex hormones and depressive symptomatology according to CES-D score were evaluated...

OBJECTIVE: Typically, about 30 to 50% of adolescents with depression fail to respond to evidence-based treatments, including antidepressant medications such as selective serotonin reuptake inhibitors (SSRIs). Efforts for identifying predictors and moderators of treatment response are needed to begin to address critical questions relevant to personalized care in adolescent depression. In this pilot study, we aim to identify biological predictors of response to antidepressant treatment...

Altered neurogenesis is suggested to be involved in the onset of brain diseases, including mental disorders and neurodegenerative diseases. Neurotrophic factors are well known for their positive effects on the proliferation/differentiation of both embryonic and adult neural stem/progenitor cells (NSCs/NPCs). Especially, brain-derived neurotrophic factor (BDNF) has been extensively investigated because of its roles in the differentiation/maturation of NSCs/NPCs. On the other hand, recent evidence indicates a negative impact of the stress hormone glucocorticoids (GCs) on the cell fate of NSCs/NPCs, which is also related to the pathophysiology of brain diseases, such as depression and autism spectrum disorder...

REVIEW
Bharath K Mani, Jeffrey M Zigman
Ghrelin administration induces food intake and body weight gain. Based on these actions, the ghrelin system was initially proposed as an antiobesity target. Subsequent studies using genetic mouse models have raised doubts about the role of the endogenous ghrelin system in mediating body weight homeostasis or obesity. However, this is not to say that the endogenous ghrelin system is not important metabolically or otherwise. Here we review an emerging concept in which the endogenous ghrelin system serves an essential function during extreme nutritional and psychological challenges to defend blood glucose, protect body weight, avoid exaggerated depression, and ultimately allow survival...

BACKGROUND: Depressed individuals often refuse or withdraw from help, a phenomenon termed help-negation, which is a risk factor for poor outcomes. Most previous research has investigated psychosocial factors including stigma as causes of low help-seeking intentions for depression, however these do not adequately explain the problem. We hypothesised that because help-negation worsens with symptom severity, it might be linked to important biological changes associated with depression itself...

The morbidity and societal burden of youth bipolar spectrum disorders (BSD) are high. These disorders are multisystemic in that adult populations there are clear interactions with inflammatory processes and steroidal physiological systems. There are much less data concerning these areas of study in youth populations with BSD. This is surprising given the association of youth-onset BSD with puberty and its associated physiological changes. In this mini-review, we overview the theoretical role of inflammatory processes and steroidal physiological systems in youth BSD, describe the greater literature in adult populations, detail the literature in youth populations when available, and overview current proposed molecular mechanistic pathways and interaction effects based on the available data...

OBJECTIVE: To estimate the association between postpartum contraception and breastfeeding among women intending to breastfeed. METHODS: We analyzed data from the Infant Feeding Practices Study II, a prospective cohort study of U.S. mothers (2005-2007). Among 1,349 women with prenatal intention to breastfeed at least 4 months who reported contraception use 3 months postpartum, we used multivariable logistic regression to estimate odds and predicted probabilities of breastfeeding by contraceptive category...

BACKGROUND: Postmenopausal women represent the largest cohort of patients with heart failure with preserved ejection fraction, and vascular dementia represents the most common form of dementia in patients with heart failure with preserved ejection fraction. Therefore, we tested the hypotheses that the combination of cardiac pressure overload (aortic banding [AB]) and the loss of female sex hormones (ovariectomy [OVX]) impairs cerebrovascular control and spatial memory. METHODS AND RESULTS: Female Yucatan miniswine were separated into 4 groups (n=7 per group): (1) control, (2) AB, (3) OVX, and (4) AB-OVX...

BACKGROUND: Alterations of the hypothalamic-pituitary-adrenal (HPA) axis are a prominent finding in patients with major depressive disorder (MDD). Inconsistencies regarding a hyper- or hypoactive HPA axis may be explained by the moderating effect of childhood adverse experiences (ACE) which are associated with both HPA axis dysfunction and MDD in adulthood. We aimed to systematically disentangle the effects of ACE and MDD on HPA axis by comparing healthy women with and without childhood adversity and women with MDD with and without ACE...

Recent studies have suggested the involvement of some metabolic hormones in memory formation and synaptic plasticity. Insulin dysfunction is known as an essential process in the pathogenesis of sporadic Alzheimer's disease (AD). In this study we examined whether adiponectin (ADN), as an insulin-sensitizing adipokine, could affect hippocampal synaptic plasticity. Field potential recordings were performed on intracerebroventricular (icv) cannulated urethane anesthetized rats. After baseline recording from dentate gyrus (DG) and 10min prior to high/low frequency stimulation (HFS/LFS), 10μl icv ADN (600nm) were injected...

Turner's syndrome (TS) is the most common sex chromosome abnormality in females and characterized with short stature and ovarian dysgenesis. Patients with TS may also present many other physical diseases and mental disorders. In this case report, we present a 49-year-old woman with TS, who also met criteria for bipolar disorder, type 2 diabetes mellitus, and autoimmune hypothyroidism. The patient was admitted to the mental health center for depressive symptoms in 1991 and was misdiagnosed as hypopituitarism, which was not corrected until 2005 when her karyotype of 45, X/46, X, i(Xq) was identified...

Objective: The facts that depression is more prevalent in females than in males and females are exposed to depression more commonly during certain hormonal fluctuating periods indicate the role of sex hormones in physiopathology. Estrogen acts over estrogen receptors alpha and beta and recently identified G protein-coupled estrogen receptor 1 (GPER1). The present study aimed, for the first time, to evaluate serum GPER1 levels in drug-naïve major depressive disorder (MDD) patients. Methods: The study included 56 newly diagnosed drug-naïve MDD patients aged between 18 and 50 years and 42 age- and gender-matched healthy volunteers...
